6 Claims.

My invention relatesA to a safety razor, and more particularly to arazor of the character mentioned which is provided with means wherebythe blade may be thoroughly cleansed without removing it from` therazor, and while the several parts of the razor and blade are in looselyassembled position.

Thev objects ofV my invention are to provide a device of this classwhich is new, novel, practical and of utility; v

The invention further comprehends the pro- -vi'sion of a safety razorconstructed so as to permit the lower guard to revolve with respect orreference to thel blade, together with means operative upon rotation ofthe lower guard for effecting a scraping of that face of the bladepresented rtoward the revolving lower guard thereby to insure a`thorough cleansing of the blade.

Another. feature and object is that it expedites athoroughvcleansing ofthe blade without requiring a disassembling of the razor therefor, andthe consequent reassembling of the parts thereof for furthen or futureuse.

It is a' further object to provide a safety razor Which may be readilycleansed after use and which will insure a positive and efficientremoval of accumulation fromthe blade without requiringv removal oftheblade from the razor, and generally to improve upon known typesv ofsafety razors.

A'further object is't'o produce' a razor" of the class described theparts of which maybe easily', quickly; and readily disassembled' andreassembled; which will be easily operated; which is simple; and yetdurable; and which will be efficient in accomplishing all'the objectsand purposes for which it is'intended,

Heretofore, some have claimed ythat the razor blade can be rinsed byloosening the parts of the Vrazor sufficiently to permit the flexedblade to return to its normal plane contour and thus become spaced fromthe guard. However, in the type of' razor blade under presentconstruction the guards and blade revolving under action of the waterduringrinsing, very often become completely disassembled, whereas, inthe present invention the possibility of the guard becoming completelyseparated from the handle is preeluded. v

With these andi other' objects inview as will more fully appear; myinvention consists in the construction, novel features, and combinationof parts hereinafter` more fully described, pointed outfin'- the claimshereto vappended-v and illustrated (ci. rsii-41) in the accompanying onesheet drawing, of which,

Figure 1 is a sectional elevational view of a safety razor embodying thefeatures of the prese ent invention, the blade being shown in its.loosed position with relation to the lower guard of the razor;

Figure 2 is a bottom plan view of the upper guard;

Figure 3 is a top plan view of the lower guard;

Figure 4 is an end elevation of the upper guard;

' Figure 5 is an end elevation of the lower guard;

Figure 6 is a transverse sectional View taken substantially on the line6 6 of Figure 1; and

Figure 7 is' a plan view showing the lower guard rotated approximatelyninety degrees with relation to the upper guard.

' Lilie characters of reference designate like vparts in all thefigures.

It Visunderstoodv that various changes in the form, proportion, size,shape, weight, and other details of construction, within the scope of myinvention, may be resorted to withoutY departing from the spirit orbroad principles of my invention and without sacrificing any of theadvan tages thereof; and it is alsol understood that the drawing is tobeinterpreted as being illustrative and not restrictive.

Referring now more particularly and in detail to the drawing, it willYbe seen the razor comprises a handle 5 which is open at its upper end,saidhandle 5 being preferably knurled, and is provided at its upper endwith internal screw threads 6, and inwardly from said end with aninternal shoulder l. The guard of the razor cornprises an upper or outerguard 8, and lower or inner guard 9. In the present instance means isprovided for positively retaining the lower guard in a fixed clampedposition between the upper guardi! and the upper end of the handle 5 orin a loose position between said upper guard 8 and handle 5 for rotationrelative thereto as desired, such'means consisting of a stem il) havingan enlarged intermediate portion i5, the lower part of which is coarselythreaded as at Il for cooperation with the thread 6- of the handle 5while theV upper portion of the enlarged intermediate part of the stemis smooth, or non-threaded, as shown. The lower guard 9 is provided,intermediate its ends with a suitable opening for receiving the enlargedportion of the stem lil, and 'on the under side is providedwith twoslightly arcuate lugs 25 for providing better surface facility-*for thecatching of the water in cleansing.'

The upper guard 8 is provided with a finely threaded aperture I3, and onthe under side of the guard 8 in line with the aperture said guard isprovided with a boss I4 which is adapted to abut the shoulder I5 formedby the enlarged intermediate portion of the stem I8 when the nelythreaded end 4 of the stem IIJ is screwed into the aperture I3 of saidupper guard 8. Y

Said stem I extends from its finely threaded end 4 through the handle 5and out at its nether end, being opposite to the end whereon said guardis disposed. On its lower end said stem I0 is equipped preferably with aknurled knob I6 arranged to engage and co-act with a shoulder I'Iadjacent said nether, or outer end of said handle 5, when the handle 5is threaded downwardly to thereby limit movement of said handle 5relative to the guard 8 when said handle is rotated in acounter-clockwise direction for loosening the lower guard 9. Knob I6 andshoulder I1 thus provide interengaging means for preventing the completeremoval of the handle 5 from the stem I8, as is apparent.

The blade to be clamped between the guards V8 and 9 is of the usual andconventional type of construction and is designated generally by thereference character I8. In the present instance the blade I8 is of awell known type of blade equipped with a longitudinal slot intersectinga series of relatively spaced apertures, and is recessed or cut-away ateach of the four outer corners, such type of blade being now commonlyused.

To retain blade I8 against rotation relative to guards 8 and 9, theupper guard 8 is provided on its under side with longitudinallyextending ribs I9 projecting from relatively opposite sides of the bossI4 and these ribs I9 are provided at their free ends with depending lugs20. At each corner of Ythe bottom side of the guard 8 said guard 8 isprovided with a depending lug 24 for co-acting with the respective fourouter co-rner cut-away portions of said blade member I8. The lower guard9 on its top side is provided centrally with longitudinally extendinggrooves 2I for accommodating the ribs I9 when the guards 8 and 9 are intheir final position for clamping the blade I 8 therebetween, it beingunderstood that the ribs I9 extend through the slot of the blade andenter the grooves 2l when the guards 8 and 9 are in their finalblade-clamping position. Likewise, the lugs extend through the openingsprovided in the blade I8 adjacent the ends of the referred to slot, andare received in arcuate transverse notches or grooves 22 providedinwardly from the ends of the lower guard 9. Thus, with the ribs I9iitting in the grooves 2 I, and the lugs 20 tting in the arcuate grooves22 the blade I8 will be secured against rotation relative to the guards8 Y and 9 when the latter are in their full bladeclamping position. Itwill also be apparent that when the guards 8 and 9 are separated asshown in Figure 1, the ribs I9 and lugs 20 engaging the blade I8 in themanner above explained and depending lugs 24 co-acting with the cut-awaycorners of said blade I8 will retain said blade I8 against rotativemovement relative to the guard 8.

The guard 9 has the longitudinal sides of its grooves 2I rising abovethe plane of the top surface of the guardrand beveled or otherwiseformed to provide parallel scraping edges 23, which edges, as shown inFigure 5 have wiping engagement with a face of the blade I8 when theparts are in the position shown in Figure 1; thus it will be seen thatwith the parts as shown in Figure 1 a rotation of the guard member 9relative to the blade I8 and guard member 8 will cause the scrapingedges 23 to move over the face of the blade and thereby remove anyaccumulations on said face of the blade I8.

The use and operation of the razor is thought to be apparent from theforegoing.

In assembling the parts, the stem I8 is rst threaded inwardly of thehandle 5, and the knob I6 attached. Next, the blade I8 is placed on theguard 8, the ribs I9, lugs 28 and boss I4 being presented upwardly topass through the slots and openings usually provided in the blade. Guard9 is then placed on top of the blade I8 with the groove 2| receiving theribs I9 and the grooves 22 receiving the lugs 28 whilev the boss I4extends into the aperture of the lower guard 9. The end 4 of the stem I9is then passed through the aperture in the guard 9 for co-operation withthe threads I3 of guard 8 to secure the guard 8 on said stem I0. Handle5 is then rotated in a clockwise direction relative to the ,stem I8 tojam against the guard 9 and thereby clamp the blade I8 between theguards 8 and 9 with the parts as suggested in the drawing. Lugs 24engage the D notched corners of the blade I8 as is apparent and theblade in its fully clamped position being flexed, whereupon the razor isready for use.

After use, and for cleaning the razor, the handle 5 is reversely rotatedfor loosening the guard 9. The razor may be rinsed by placing it undera. spigot and running the water thereover, whereupon guard 9 will becaused to rotate relative to the guard 8 and blade I8 with the ribs 23scraping one face of the blade I8 to thereby loosen and remove anyaccumulations on the blade. Perpendicular blades or wings 25 areprovided beneath the guard 9 for expediting rotation of the guard by therunning water.

Thus it Ywill be seen that an effective rinsing and cleansing of therazor and blade Vmay be readily effected without requiringa completedisassembling of the parts.

Obviously the invention is susceptible of embodiment in forms other thanthat which is illustrated in the accompanying drawing and describedherein, and is applicable for uses and purposes other than as detailed,and I therefore con- Sider as my own all such modifications andadaptations and other uses of the form of the device herein described asfairly fall within the scope o-f my invention.

Having thus described my invention, what is Vclaimed and desired to besecured by Letters Patent, is: Y
